To all '1r/1on1 t may concern Beit known that I, JONATHAN PERKINS, Jr.,a citizen of the United States, and a resident of San Diego, county ofSan Diego, State of California, haveinvented a certain new and usefulGravity-.'\.ctuated Pipe-Laying Apparatus, of which the following is aspecification.

My invention relates to an apparatus for handling and placing inposition the different sections of pipe, preferably concrete pipe andthe objects of my invention are, first, to provide an apparatus tofacilitate the laying of large pipe, second, to provide such anapparatus that is simple, easily constructed and easily operated, andthird, to provide such an apparatus in which the parts are adjustablefor different sized pipe sections.

With these and other objects in view, as will appear hereinafter, myinvention consists of certain novel features of construe tion,combination and arrangement of parts, as will he hereinafter describedin detail and particularly set forth in the appended claims, referenceheilig had to the accompanying drawings and to the characters ofreference thereon, which form a part' of this specification, in which:

Figure l is a side elevational view of my device in the preferred formshown in connection with the pipe section with parts of the pipe hrokenaway and in section t0 facilitate the illustration, Fig. 2 is an endview of the pipe showing the tripod in p0sition, Fig. 3 is a sideelevational View of my pipe carriage shown mounted on a fragmentaryportion of this support and showing `a section of pipe mounted thereonin section, Fig. 4 is a top or plan view of a fragmentary portion ofsaid carriage, Fig. 5 is a transverse sectional view taken through A-Bof Fig. 3.

SimilarI characters of reference refer to similar parts throughout theseveral views.

The tripod l, carriage 2, carriage support 3, and jack 4, constitute theprincipal parts 'of my device..

The tripod 1, consists of a straight portion threaded almost its entirelength and bifurcated at its top end 1n. t is mounted in a support l'bwhich is provided with an in ternal thread adapted to fit the thread onthe screw on the main portion l. Over this thread in the main portion lis provided a nut l on Specification of Letters atent.

which are rigidly mounted at angles to said main portion 1, legs i@ andl whichl arend justaoly mounted in supports?. Mounted on this tripod inthe slot between the hifurcated membersl is a T 'oar 3 adapted for thesupport for the carriage 2. @ver this support is mounted the 1codyportion 2 of the carriage, shaped as shown leest in Figs. 3 and 5. lt isprovided with two longitudinal axis rollers 2l adapted for supportingthe pipe section, which section may'.A he turned thereon. t is supportedhy means of two transverse axis rollers 2 which are provided withflanges adapted to roll on the upper surface of the support 3 to reducethe friction of the movement of the carriage. The other end of thesupport from the tripod'is supported oy means of the jack t which is anordinary jack except that it is provided with hifurcated top ends 4aadapted to fit the downwardly extending member of the support 3.

lt is obvious that with this apparatus there is provided a device thatwill greatly facilitate the placing ofthe different sections of pipe,

that by adjusting the tripod l to the proper A height, placing thesupport with the carriage thereon through the pipe sectionh placing ajack 4 under the other end and raising the simple of construction andeasily operated.

Having thus described my invention, what l claim as-new and desire tosecure by Letters Patent, is:

l. In a gravity actuated pipe laying apparatus an adjustable tripod, anormally horizontal bar with one end mounted thereon, a carriage mountedou said har and prov vided with rollers to facilitate its movementthereon, horizontal aXis rollers mounted on said carriage so that theirupper surfaces extend above said carriage and means for raising andlowering the other end of Said bar.

2. A gravity actuated pipe laying apparatus, comprising an adjustabletripod with hifurcated upper end, a normally horizontal T bar with oneend mounted. thereon, a carriage mounted on said T bar and fitted riego'provided with arouoe he seme and adapted to fravel =thereon, and a jackthe upper end of which bfuroated to 'iig-said T ber for raising the endthereof. :i :j

3. A gravity` actuated -ppe laying appeetq, comprising a-tripod, eachmember o whlh s adjustable, a normally horizontal Darwith one endfmounted thereon, endlv adapted tozt the upger end thereof, aeerorizontal axis rollers,

lhounted enea-id bar and adapte to travel thereon, and a jock which isadapted to fri; said bar for raising the other end thereof.

In tespmony whereof, I have hereunto subscribed my name in the presenceof two
